Williamson County, Texas
Williamson County is the northern engine of the Austin metro: Round Rock, Dell's headquarters city, and Georgetown — repeatedly the fastest-growing city in America — plus Leander, Cedar Park and Hutto. Samsung's $17 billion fab at Taylor is remaking the county's rural east, and school districts plus the 183A and SH 130 toll corridors set the growth map.
